this control clockwise to switch on the unit. Turn the knob clockwise a little
more to set the audio level, until you get a comfortable reception.

noise and to operate in DS (Digital Squelch) mode.

positioned on CH 9 (emergency channel). The display will show "EMG". It will
not be possibile to accidentally change the channel.
7. "Q. UP" button: To skip 10 channels up (Q. UP).
8. "Q. DOWN" button: To skip 10 channels down (Q. DOWN).
9. "AM/FM"(LCR) button: To select AM or FM mode. If you push it along with
the "SCAN" button at the switching on of the radio, it selects the operating
band, which will be displayed. If you select a frequency band operating in FM
mode only, this button enables the LCR function (Last Channel Recall).
10. "SCAN/NB" button: with this control, you can automatically seek
for a busy channel. Turn the Squelch clockwise until the background
noise is no longer heard. Press the ''SCAN'' button: the transcei-
ver will scan automatically all the channels until a carrier is being recei-
ved. If you push it along with the "AM/FM" button at the switching
on of the radio, it selects the operating band, which will be displayed.
Keep pressed this button to activate the Noise Blanker filter.
